Though, one should keep in mind that this is a general recommendation and the frequency with which you need to clean your house’s air ducts can change based on various other facts.

Taking proper care of one’s house, its surroundings and other such factors can reduce the need for frequent cleaning of these air vents; on the other hand, a buildup of mould and other contaminants leading to adverse reactions may demand a more immediate air duct cleaning.

Cleaning the components of a heating and cooling air duct system may enhance your system’s performance, resulting in a longer operational life as well as some energy and maintenance cost savings. Thus regular cleaning can be beneficial.

This dust can then settle in the  components of the air ducts and reduce its efficiency, hence it is a great idea to get the air ducts of your home cleaned once you are done with the renovation work.

3. Smoking indoors

It is also concerning when the air ducts of your home start throwing out excessive dust into the air. This is a clear sign that the duct needs to be cleaned.

The growth of molds around your house is a sign that the air inside your home is not very clean. This also leads to a musty smell indoors. If that is the case with your home, it would be highly advisable to get the air ducts cleaned. This will not only reduce the growth of mold but also improve the air quality of your home.
